Hellow welcomegee I emailed the photos of my pcb as you instructed. I still cannot remove the small white ribbon cabled that connect the three PCB so I can take the middle pcb out to solder the new IC's

Although it may be done, i think replacing the circut board rather than the ic would be the answer to this one. Even if you have the equiptment and the skills it takes to succesfully replace the ic, chances are ,a critical circut malfunction occured damaging you chip. The same result may happen again with the new ic.
I would consider pricing either a circut board or a new display all together.

I don't know if you can buy the boards anymore, ive always replaced the IC checked the resisters, i can point you to two websites that have instructions.http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.htmlhttp://home.earthlink.net/~oleg.filippov/ConvergenceFix.htmi would also replace the IC with the stronger ones stk392-180's and i would replace both no matter what.

Good Day,
Check these two areas: 1. CHECK IC700 PIN 4 (AC-OFF) FOR 0 VOLTS DC, IF HIGH, CHECK FOR LEAKY D980 PART # 264P045040 ON THE MAIN PCB. 2. CHECK FOR 4.7 VOLTS DC AT CONNECTOR RF PIN 3 AND 4 ON THE SIGNAL PCB IF LOW SUSPECT PROBLEMS WITH THE SWITCHES/BUTTONS ON THE CONTROL PCB PART # 935D394001. 2). CHECK FOR 10 VDC AT PIN 5 OF IC502 OF LOW, CHECK IC503 PART # 270P704010 ON THE MAIN PCB. 2. CHECK R529 .82 OHM 1/2 WATT OFF PIN 4 OF THE FLYBACK. IF OPEN CHECK C411 2200 UFD @ 35V AND IC 451 PART # 270P064020. ON THE MAIN PCB. Good Luck, big IRISH.

Convergence PCB probably not available....can you get me any #'s off the PCB or part # of STK IC or location # of convergence IC ??? ..................Should be worth fixing if I can get alittle more info....................T.

Note to mountain mom: You have a completely different
symptom ..............+ need service #.............
Try DVD ? all inputs ? cable box ? source to RF coax= on ch.3 ?..............................T.

FIRST CHECK CONNECTOR "DR" FOR PROPER CONNECTION, BETWEEN THE DEFL MINI PCB AND THE MAIN PCB. 2. CHECK C5A09 AND C5A50 BOTH 33 UFD 50 V OFF OF IC5A01 ON PCB-DEFL MINI. 3. CHECK FOR LEAKY IC5A03 PART # 270P704010 ON PCB-DEFL MINI 4. SUSPECT THE HIGH VOLTAGE BLOCK PART # 920P016010 IF STILL NO HELP PROBLEM CAN BE INTERMITTENT (TEMPERATURE RELATED) CAUSED BY IC7D04 PART # 275P245010 ON THE DOUBLER PCB THIS WOULD BE A THIN VERTICAL LINE IN CENTER, IF GUNS WERE ON.
